"A moment ago This company is great. Roy Villa the service technician was very knowledgeable. No threat of up selling. Just explained what was wrong with the heating system and fixed it. This is for a rental house. He told me about the warranty plan they have for heating and AC. It was extremely reasonable. Now I will just have the AC and heater checked before each season."

"We hired Airmercia Air Conditioning & Heating to evaluate our heating system and propose repair solution. Ryan was very professional and punctual. He did not make any force sales. He just offered various repair and replacement solutions and explained pros and cons for each one. We decided to replace our furnace and duct system. Ryan did an excellent Job!! I highly recommend him for your HVAC project."

"I had been told by another company that my HVAC unit needed to be replaced for $3500.  However, the technician didn't even look at the unit.  So I subscribed to Angie's list and chose Liberty for a second opinion.  Apparently all that was needed was to add coolant; the level was very low.  My AC is now working better than ever.  Thank you Liberty and Angie's list for saving me over $3000!

"Technician Angel came on time. He first cleaned our HVAC unit, checked the wirings & parts & performed tests to ensure the unit is running according to standards. He inspected the Air ducts, vents even the attic. He explained everything and showed us the pictures that he took & the results on HVAC heating and cooling tests that were done. Overall a very good job done by Technician Angel I told him to come back after 6 months. Already recommended Airtime Heating & Cooling to my neighbor. 5 STARS"

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Friendly customer service and professionalism. Two guys serviced the unit and check each room in the house, as well as the inside returns and filters. They made recommendations regarding vent settings and leaving room doors open to improve return airflow."

Heating and Air Conditioning questions, answered by experts

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible.
